The 3-chloroperoxybenzoic acid oxidation of dimethylhydrazones of aromatic aldehydes gives the corresponding nitriles in good yields. Two further examples of the same oxidative transformation of cinnamaldehyde and of hexanal are also given. Except for hexanal hydrazone, all other aldehyde hydrazones can also be efficiently converted into nitriles by treatment with methanolic 30 % hydrogen peroxide in the presence of catalytic amounts of selenium dioxide or, preferentially, 2-nitrobenzeneseleninic acid.
芳香醛的二甲基脒经3-氯过氧苯甲酸氧化后,以良好的产率得到相应的腈。还给出了肉桂醛和己醛的另外两个类似的氧化转化的例子。除了己醛脒之外,其他所有的醛脒都可以通过处理与含甲醇的30%双氧水在二氧化硒或更优选的2-硝基苯硒酸催化量的存在下高效转化为腈。
